Definitions

  • the present invention relates to a washing machine for cleansing clothes. It relates more particularly to a washing machine that spins a washing basket containing clothes, thereby generating centrifugal force which produces a water stream, and the water stream runs through the clothes, so that soil is removed from the clothes.
  • a conventional washing machine in general, employs an agitating method. That is, a user puts the clothes into a washing basket doubling as a spin-dryer (hereinafter referred to as a “basket”) in the first place, then supplies water into the basket up to a given level. After that, the user agitates the agitator (pulsator) disposed in the basket to cleanse and rinse the clothes.
  • a washing basket doubling as a spin-dryer
  • the agitator agitates the agitator (pulsator) disposed in the basket to cleanse and rinse the clothes.
  • the agitating is performed by repeating the steps of clockwise spinning, halting, counterclockwise spinning of the pulsator, halting. Respective periods of clockwise spinning and counterclockwise spinning are determined at a given duration so that the clothes are sufficiently agitated. The halt period is also determined at a necessary time for starting the reverse spin after the agitating has been halted.
  • the pulsator agitates the clothes, and the pulsator contacts the clothes directly or via water, thereby revolving the clothes to be cleansed.
  • This structure produces a powerful cleansing effect; however, the clothes directly contact the pulsator, so that the clothes become vulnerable to damage.
  • the clothes frequently move and revolve up and down, and left and right, whereby the clothes get entangled in a complicated manner with each other.
  • the centrifugal force due to spinning the basket in the next step i.e. dehydrating; is impressed to the clothes, whereby the entangled clothes are forcibly stretched and pressed onto an inside wall of the basket.
  • the clothes lose their shape, and are hard to take out from the basket after the dehydrating step.
  • the present invention addresses the problems discussed above and aims to provide a washing machine where only movements of the water only work to on articles to be cleansed so that the articles are kept free from damage and entanglement.
  • the washing machine of the present invention comprises the following elements:
  • the control device is so structured that it spins the basket, and varies centrifugal force applied to the water in the basket in order to cleanse the articles.
  • the structure discussed above allows the water stream including detergent to run through the fibers of the clothes thereby removing soil from the articles. As such, because the articles receive only the force due to water movement by the centrifugal force, the articles can be cleansed without damage and entangled.
  • FIG. 1 is a cross section of a washing machine in accordance with a first exemplary embodiment of the present invention.
  • FIG. 2 is a block diagram of a circuit of the washing machine shown in FIG. 1 .

  • FIG. 1 is a cross section of a washing machine in accordance with the first exemplary embodiment of the present invention
  • FIG. 2 is a block circuit diagram of the washing machine shown in FIG. 1 .
  • a water tub 1 has a washing basket doubling as a spin-drier 2 therein.
  • the washing basket doubling as a spin-drier 2 is referred to as a “basket 2 ”.
  • Water tub 1 is suspended by a suspension rod 3 from an outer frame 4 so that vibration due to spinning of the basket and rotating of the driving machine, e.g. motor 5 , is restrained.
  • Motor 5 spins basket 2 , and the rotating speed of motor 5 is controlled by a control device 6 .
  • a water valve 8 supplies tap water to water tub 1 .
  • a drain valve 7 drains cleansing water in the washing machine outside the machine.
  • a lid 9 covers a top section of basket 2 , and articles, e.g. clothes 10 are loaded into basket 2 .
  • Spinning basket 2 generates centrifugal force, which works on the cleansing water in the basket, so that the cleansing water rises toward the inner wall of basket 2 .
  • the surface 11 of cleansing water forms a conical shape, in other words, a parabolic line from a cross sectional view in a broken line as shown by a broken line in FIG. 1 .
  • control device 6 is structured as follows: a controller 12 comprising a microcomputer controls respective steps of cleansing, rinsing and dehydrating based on a mode set by an instruction through a operation panel 13 . To be more specific, controller 12 controls motor 5 via a motor driver 14 . Controller 12 also controls water valve 8 and drain valve 7 via a power switch 15 . A storage 16 stores necessary data for controlling by controller 12 .
  • a rotor-positioning-detector 17 receives a signal from motor 5 , and detects a position and rotating speed of a rotor, and then outputs the detection results to controller 12 and to a clothes-load-determiner 18 . Based on the data from rotor-positioning-detector 17 , clothes-load-determiner 18 determines an amount of clothes, and outputs the result to controller 12 .
  • a water level detector 19 detects an amount of water in water tub 1 , and outputs the result to controller 12 .
  • a power supply circuit 20 e.g. rectifies and smoothes the commercial power 21 of ac 100V into a dc voltage, and then powers motor driver 14 .
  • Power supply circuit 20 also, e.g. lowers that dc voltage to dc 5V to operate controller 12 .
  • a power switch 22 is coupled to commercial power 21 , and turns on and off the power.
  • Controller 12 controls the spin of basket 2 by controlling motor 5 , thereby varying the centrifugal force working on the cleansing water in basket 2 to cleanse the clothes. Controller 12 varies the centrifugal force by spinning basket 2 intermittently or varying the spin speed periodically.
  • FIG. 3A shows a variation of spin speed with regard to the time lapse when basket 2 is spun intermittently.
  • FIG. 3B shows a variation of spin speed with regard to the time lapse when basket 2 is spun by varying the spin speed periodically.
  • the intermittent spin of basket 2 is described with reference to FIGS. 3A, 4 A and 4 B.
  • clothes 10 is distributed in basket 2 almost uniformly, and the surface of the cleansing water stays level as shown in FIG. 4 A.
  • This intermittent spinning and cleansing power of the detergent causes the soil to be readily removed from the clothes.
  • the centrifugal force removes the soil from the clothes, and draws some of the soil having a greater specific gravity than the cleansing water to the outside, while drawing the soil of a smaller specific gravity to the inside. The clothes are thus cleansed.
  • the variation of spin speed as shown in FIG. 3A varies the centrifugal force.
  • the surface of the water in basket 2 varies from a level to a conical shape and vice versa as shown in FIG. 4 A and FIG. 4 B.
  • This change moves the clothes from the center to the circumference and vice versa, which produces a press-washing effect. This effect contributes to removing soil from the clothes.
  • Varying the spin speed of basket 2 periodically is another method to cleanse clothes, which is described hereinafter.
  • the spin speed of basket 2 is increased along the time scale from t 0 to t 5 .
  • This method also produces the same effect discussed previously and shown in FIG. 3 A. Because the variation of centrifugal force becomes smaller than in the previous case, the cleansing power per variation cycle decreases. However, frequencies of variation of spin speed are greater than in the previous case. This method can thus often gain stronger cleansing power per period than the previous method. Either one of the methods shown in FIG. 3 A and FIG. 3B can be selected as required.
  • clothes 10 into are loaded basket 2 , an then a start-switch (not shown) disposed on operation panel 13 is pressed, which drives motor 5 for a given time via motor driver 14 based on an instruction of controller 12 .
  • the operation data of motor 5 during this given time is detected by rotor-positioning-detector 17 , and transmitted to clothes-load-determiner 18 .
  • Determiner 18 determines load data of the clothes and inputs it to controller 12 .
  • One of the load determination methods involves e.g. transition of rotating speed of motor 5 during the given time based on the signals from detector 17 , and then the load of the clothes can be determined.
  • Controller 12 instructs power switch 15 to open water valve 8 , which starts supplying water to water tub 1 .
  • Water-level-detector 19 monitors a water level of tub 1 , and inputs the report to controller 12 .
  • controller 12 determines that the water reached a level appropriate to the clothes load, controller 12 instructs switch 15 to close water valve 8 , and stops supplying water.
  • Controller 12 then drives motor 5 via motor driver 14 , and moves the process to the cleansing step.
  • controller 12 controls motor 5 to rotate intermittently as shown in FIG. 3 A.
  • the maximum spin speed n 2 of basket 2 is set based on the water volume, and the maximum spin speed n 2 is increased at lower water volume. In other words, when tub 1 contains less water volume, the smaller load is applied to motor 5 , thereby increasing the spin speed.
  • the spin speed is increased, the cleansing water won't splash out from the top of the basket, which allows the spin speed to increase.
  • the centrifugal force increases at the higher spin speed, so that the cleansing power becomes stronger. As a result, a cleansing time can be shortened when water is at a low level.
  • drain valve 7 is opened for draining the cleansing water. Then, rinsing and dehydrating steps are carried out before the washing is completed.
  • the centrifugal force due to the spinning of basket 2 forces the cleansing water to run through the fibers of clothes, and produces a press-washing effect, whereby soil can be removed from the clothes.
  • the clothes are thus cleansed without being damage, losing their shape or being entangled.
  • Clothes-load-detector 18 gives the data clothes load to controller 12 so that controller 12 can vary the water level based on the data. As a result, the clothes can be cleansed with an appropriate volume of water, which saves water and detergent.
  • basket 2 having dehydrating holes is described as an example; however, a basket doubling as a spin-drier with no holes can also produce the same effect.
  • FIG. 5 is an operational timing chart of a washing machine in accordance with the second exemplary embodiment of the present invention.
  • the points in the second exemplary embodiment which are different from the first embodiment involve the manner of driving basket 2 which doubles as the spin-drier. Other structures remain the same as in the first embodiment.
  • Controller 12 shown in FIG. 2 varies at least respective periods of driving and halting of basket 2 in an intermittent driving manner, or varies cycles of varying a spin speed of basket 2 , based on a water level, the clothes load, and the kind of clothes.
  • a method of cleansing is changed responsive to the kind of clothes.
  • a woolen sweater has totally different delicacy of fiber and constitution of soil from those of a cotton underwear.
  • fibers are entangled with each other, and crinkled, while the cotton is not so delicate as the woolen sweater.
  • the cotton underwear is soiled with fatty skin, but the woolen sweater is lightly soiled. Accordingly, the woolen sweater does not demand so much cleansing power, and is desirably washed free from moving.
  • the cotton underwear may be moved during the washing and it demands cleansing power.
  • FIG. 5 illustrates the specific cleansing ways for these two types of clothes.
  • FIG. 5 shows how to control the spin speed of basket 2 .
  • Solid lines 50 show the spin-speed-control for cleansing the woolen sweater
  • broken lines 60 show that for the cotton underwear.
  • a start-up spin speed varies in a narrow range, and the frequency of repetition is controlled to be a small number so that the sweater does not move so much.
  • the start-up speed varies in a wide range, and the frequency of repetition is increased so that the underwear moves well.
  • the manner of varying the spin speed of basket 2 produces an appropriate cleansing method for the respective clothes.
  • the spin speed can be thus controlled little by little.
  • the cycle of spin speed variation can be shortened in order to increase the cleansing power so that the cleansing period can be shortened.
  • the cycle of spin speed variation can be thus changed, whereby an appropriate cleansing method is produced as well as the cleansing period can be shortened.
  • FIG. 6 is an operational timing chart of a washing machine in accordance with the third exemplary embodiment of the present invention.
  • a point different from the first embodiment is the manner of spinning basket 2 .
  • Other structures remain the same as in the first embodiment.
  • Controller 12 shown in FIG. 2 can alternate a spin direction of basket 2 .
  • An operation of the third exemplary embodiment is described hereinafter.
  • the spin speed of basket 2 is controlled as shown in FIG. 6 .
  • the Y-axis of FIG. 6 represents spin speeds, and a speed of clockwise spin increases upwardly from the center, i.e. “0” (zero), while a speed of counterclockwise spin increases downwardly from the center “0” (zero).
  • basket 2 spins clockwise and is the spin is increased in speed, and then stopped. Although the spin is halted, the inertia moment of basket 2 per se keeps basket 2 spinning but with decreasing speed. When the spin speed reaches almost “0” (zero), basket 2 is driven to spin counterclockwise. Then the spin is increased speed and then stopped. The inertia moment of basket 2 keeps basket 2 spinning but with decreasing speed. When the spin speed reaches almost “0” (zero), basket 2 is driven to spin clockwise. One cycle is thus completed.
  • controller 12 alternates the spin direction of basket 2 every spin; however, controller 12 can alternate the spin direction after a plurality of spins in the same direction, which also produces the same effect.
  • FIG. 7 is a cross section of a washing machine in accordance with the fourth exemplary embodiment of the present invention
  • FIG. 8 is a block circuit diagram of the washing machine shown in FIG. 7 .
  • a water-guard 23 is disposed on water tub 1 . Due to spinning of basket 2 , cleansing water rises into an annular space between basket 2 and water tub 1 . The rising water forms a waterfall 24 toward the inside of the basket 2 , and sprays over the clothes 25 and 26 . At this moment, the surface 27 of the cleansing water in basket 2 forms a conical shape as shown in a broken line.

  • a storage device 33 stores data necessary for controller 29 .
  • a rotor-positioning-detector 34 receives signals from motor 5 , and detects a rotor position and its rotating speed.

  • a water-level-detector 36 detects a water level in water tub 1 , and outputs the result to controller 29 .
  • a power-supply-circuit 37 rectifies and smoothes the commercial power 21 of ac 100V into a dc voltage, and then powers motor driver 31 .

However, clothes 25 cannot be cleansed at this location.
  • the second step discussed above is then introduced, i.e. the spinning of basket 2 allows the cleansing water to form the waterfall 24 and spray over clothes 25 from the location of water guard 23 . Since basket 2 spins, centrifugal force allows the cleansing water to run through clothes 25 , thereby cleansing them.
